## Why this should be merged
I messed up the format of `rc` version tags, resulting in `rc.1` being
considered a later version that `rc.2`.
## How this works
The [release tagging](https://github.com/ava-labs/libevm/discussions/37)
pattern that includes a combination of `geth` and `libevm` semver
triplets (e.g. `1.13.14-0.1.0`) doesn't work well with extra identifiers
like `rc` because more pre-release identifiers (those after `-`) take
higher precedence if all those before them match. We therefore have to
use a `release` suffix (`"release" > "rc"` in ASCII).
This all became too much to expect to be done manually so I chucked it
in code instead.
## How this was tested
Unit test demonstrates expectation of version ordering.
